Description

200836689 IX. INSTRUCTIONS: [Technical Field] The present invention relates to the technical field of oil-repellent fabrics, and more particularly to a fabric having oil-repellent and oil-free flaws after rubbing and a method for preparing the fabric. [Prior Art] In general, the preparation process of the anti-oil fabric includes dyeing, drying, surface antifouling treatment, post-inspection, packaging, and shipping. Among them, the surface anti-fouling system

The process is based on fluorocarbon or hydrazine water repellent as the main formula for surface antifouling treatment. However, if the surface of the fabric treated with the general antifouling treatment is stained with oil, it will not completely remove the oil after wiping or washing, and the oil residue will remain. "It affects the appearance of the fabric. In addition, if the fabric is stained with oil and has a lot of oil After the secondary washing, the fiber structure of the fabric will be changed, and the effect of the fabric will be greatly reduced. At present, there are anti-oil products on the market, but there is no product with no oil-scraping effect after wiping. Therefore, it is urgent to develop a kind of anti-oil and easy to clean. And the oil-free crater after wiping is often kept clean and beautiful, and the woven fabric is rushed to meet the needs of current and future functional fabrics. [Invention] In order to improve the disadvantages of the above-mentioned conventional grease-proof fabrics, the present invention The main purpose of the invention is to provide a fabric which has the effect of preventing oil staining and having no oil-scraping after wiping. The fabric having the oil-free flaking effect after the oil-proof phantom cleaning has _ the bottom layer (und coffee) and the oil-proof protective film It can effectively prevent the oil from invading the surname and penetrate and infiltrate the surface of the fabric. Therefore, there is no oil residue after wiping. Ben!, Mingzhi--The purpose is to provide - oil-proof and oil-free after wiping 115605 200836689 The preparation method of the effect fabric comprises the following steps: the fabric is placed in the smear, the wood color, the bottom sound, and the Yiyi treatment to form the surface of the fabric to prevent oil stains. Processing to protect the oil-repellent protective film. _(3) Surface formation The fabric of the present invention may be any synthetic, woven fabric such as, but not limited to, polyacetic acid, polystyrene, rare, N/C, T /C, CVC or leather. 较佳 Ο Ο = hair: in the preferred embodiment of the 'the surface of the fabric system', such as but not limited to corona, atmospheric electricity or reduced processing to roughen the surface, and then The underlayer is processed to the surface of the fabric.
